turbo 3400?

Post by JeffD »

Hmmm. makes sence. I was looking on V6z24 forum for turbo stuff and saw that one member has a turbo cavy with close to 400 hp. Thats what i'm looking for.
Berettaspeed, you said that the tranny for the V6 was perfect, are you talkin auto or manual?

Whoops... your right, midnightriderz24 has 35X Hp. my bad, i saw someone asking about 400hp. but what would it take to get that?
What kinda times would i be looking at in a 1/4 mile?
I've looked around on ebay and can't find GTP injectors, Can i get them out of Bonnevilles or other supercharged v6s?
Well, I lost the beretta that i thought i could get for my turbo car  still on the lookout.

I might have an extra set of L67 Injectors if that is what you're looking for.  PM me if interested.

are those the ones from the supercharged 3800? I don't know the option code.
well the turbo project is going to get delayed a couple of weeks, my 2.8 just crapped the bed again. put a wrist pin right into the cylinder wall and ruined the block... sweet. so before I work on the project engine i have to fix my daily driver.

How would you install a boost pressure sensor for a gauge and where?
also can you use a tgp PROM for a baseline setup to modify on the computer? or does that not really matter?

ok boost gauges use a hard nylon or copper tube tapped into the manifold to read boost it runs all the way to the gauge.  The tgp chip will work but you need to get bigger injectors, thread in iat moved to the manifold, 2 bar MAP sensor (you'll need to change the connector as well), oh and it still won't run very good usually. your speedo will be way off, it won't idle worth a fart, and the motor may just run like crap.  You need to change a lot in the code but then it will run damn fine.

since the motor is gone, just look for a late 3100 or 3400. and turbo that.

Oh I wish, but i need the gas milage for going to school, I go over 100 miles a day back and forth. =( I would move up closer to rochester, but my GM dealership that I work at for school is here in waterloo.
I already have the 3400, 3800 injectors and tuning software. still looking for a car.
I've got the 2.8 back on the road and load as ever!  I love pounding civics!
let the turbo project commence!

Should be.  The model for the old GN may be a direct fit and plug in if you do a little work to the plug (or swap key's on the MAP sensor plug-in).

I tried looking for a map sensor on a supercharged Riviera but couldn't find it, maybe someone already got it. where would it be?
